BUCKET-ELEVATOR FOR FL OURING-MILLS.

SPECIFICATION forming part of Letters Patent No. 415,819, dated November26, 1889.

Application filed July 31, 1889. $en'a1 No. 319,351. (No models) To allwhom it may concern.-

Be it known that I, WILLIAM J ETHRO PURDY, of Oarberry, in the county ofNorfolk, in the Province of Manitoba, in the Dominion of Canada, haveinvented a certain new and useful Improvement in Bucket-Elevators forFlouring-Mills; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being bad to To theaccompanying drawings.

Figure 1 is a section of a portion of a bucketelevator, showing mycleaner or brush applied thereto. proved elevator on the line as as,Fig. 1. Figs.

3, 4c, and 5 are perspective views of detached portions of the brush toshow the construction.

My invention has for its objects to remove the accumulation of flouradhering to the trunk or tube of flour-elevators, and thereby preventflour from being deteriorated by the accumulation loosening afterbecoming musty and mixing with the Hour, and also, by removal of suchaccumulation, to prevent the tube or trunk from becoming rotten, becauseof the dampness in the adhesive particles of flour.

My invention consists in securing to the elevator-belt, and between thecups or buckets thereon, one or more brushes which will sweep threesides of the trunk and thereby prevent accumulation of flour adhering tothe interior.

A is the endless belt, B the cups or buckets, and C the tube or trunk ofthe elevator as used in flouring-mills.

D is a brush riveted to the belt, and has frictional contact with threesides of the elevator-tube O to sweep off particles of flour, which,owing to the heat and moisture generated in manufacturing or grinding,cling to the sides of the elevator-trunk, and if not removed becomemusty, rot the trunk, and injure the fiour.

Fig. 2 is a section of my i1n- The brush D is preferably composed of ametallic rectangular frame E, having a central opening J, and providedwith a flange 2, which is secured to the belt by rivets or bolts F tohold the brush at right angles to the belt, and to said frame E issecured a U- shaped cover-plate G, corresponding to three sides of frameE and placed one over the other.

H H are flexible plates of rubber, cloth, leather,orother suitablematerial intervening the frame E and cover G and project from theoutside edge on three sides, and between said plates III-I andprojecting therefrom is secured a brushing I, of bristles, steel Wire,or other suitable material, by bolts or rivets 6o 3, which pass throughand compress together the frame E and cover G to hold the plates H H andbrushing I interveningly. The brushing I sweeps the finer particles offlour which have adhered to the tube during the operation of theelevator, and the dislodged material passes through the aperture J inthe brush and falls into the bucket or cup below.

I claim as my invention 1. The combination, with the elevator-tube O andendless belt A, having cups orbuckets B, of an open-framed brush D,having one side attached 'to the belt and its bristle or wire endsarranged in frictional contact with three sides of the tube, as setforth.

2. The combination, with the elevator trunk or tube 0 and endless beltA, having buckets or cups B, of a brush D, provided with a centralaperture J and secured to the So belt to sweep three sides of the trunkor tube, as set forth.
